I don’t particularly care for the idea of lightsaber duels as an Olympic sport, but I could easily see it as a televised combat sport. Solo and team. Done right, it could be quite fun to watch.
Note: I’m taking the fun of participation to be self-evident. (I used to do NERO sparring.)
Tangential note: when I was in high-school, a bunch of us used to play “Tron”. Inspired by the disc game in the movie, we closed a door on a vacant classroom and swatted a superball around with notebooks, textbooks or ring binders. All ricochets were live unless they bounced off of another player. If you were hit, you were “derezzed”. Nobody used any protective gear. No desks or chairs were rearranged, so they were part cover and part hard obstacle that could mess you up if you collided with it the wrong way...
